Description

Calculate the image processing system of consumes power

Japanese patent application No.2011-222404 and No.2011-222536 that the application proposed to Japan Office based on October 7th, 2011, its all the elements are quoted so far.

Technical field

The present invention relates to image processing system, particularly relate to the image processing systems such as duplicating machine, facsimile recorder, various printers.

Background technology

There is the MFP(MultiFunctionPeripheral with scan function, facsimile function, copy function, function, data communication function and server capability as printer in the image processing system of electronic photo formula), facsimile recorder device, duplicating machine, printer etc.

Because the discharge rate that is surging, the surging or carbon dioxide of economizing energy ambition of the care of the environment to the world cuts down the surging of ambition, the expectation of the consumes power of cutting down with MFP the image processing system being representative is improved.In order to use image processing system with the method can made contributions to electric power saving (not violating the method for electric power saving), image processing system is used with the method not violating electric power saving, or confirming the reduction reliably can implementing electric power for making user, proposing the function of the consumes power of display image processing system, the function etc. of the consumes power of image processing system is provided to the computing machine etc. outside image processing system via network.But, precision is measured well or the technology of consumes power of computed image forming apparatus, is not also fully suggested.

Originally, the consumes power of image processing system changed according to the operating state of image processing system.Such as, N-free diet method time, the state that can print and holding state are more than the power consumption of the state and electric power saving state that make the function stop of a part.In addition, the power consumption that the state that image processing system carries out colour print carries out the monochromatic state printed than image processing system is many.For the function of existing display consumes power, when changing the setting involved by the power saving functions such as setting involved by the time before shifting to electric power saving state when user, image processing system starts and recommends the situation of the monochromatic pattern printed inferior, pay attention to user can consumes power after physical experience to specified time limit with before consumes power compared with decrease.Therefore, and think little of the height of the precision of the consumes power shown, do not take the countermeasure that the precision of consumes power is improved.

But, surging due to the sense of crisis to greenhouse effects of the earth, and the motion in the world of the discharge reduction of carbon dioxide is advanced with concrete numerical target, its situation is also in change.Such as in company, office, usually pass through various equipment such as the air-conditioning within the scope of its management object, image processing systems, obtain " power consumption reduction ", " the discharge reduction according to the carbon dioxide that power consumption reduction calculates " by each equipment, carry out the discharge reduction of management of computing object range entirety.And then, for the equipment not reaching the target of discharging reduction, usually perform further improvement measure.As a result, the high precision of the power consumption information that image processing system provides be sought.

In addition, the consumes power of various equipment, each equipment account for the ratio of the consumes power of wastage in bulk or weight electricity with seasonal variations.Such as, the power consumption of air-conditioning changed with season, but was almost constant between the power consumption such as elevator whole year.Therefore, distribute to the power consumption reduction of each devices such as image processing system, target consumes power monthly different, need compared with the same month of upper one year.That is, just from epoch changed qualitatively of the consumes power of seeking to understand image processing system to the era change of the quantitative change of the consumes power of seeking to understand image processing system.

Existing existing method of seeking the consumes power of image processing system such as discloses in following document 1 and 2.

Disclose in following document 1 based on printing setting, printing number and the count results of printing number, calculate the technology of energy-conservation degree.In the technology of following document 1, the calculating of consumes power is set as " power consumption=(power consumption A during duplicating) × (print run time X)+(power consumption B during dormancy × (in dormancy time Y)+(power consumption C during FAX) × (the FAX Z duration of runs) ".Suppose that above-mentioned fixed value A, B and C can be arbitrary fixed values.

Disclose following technology in following document 2, namely by AC/DC transducer, the alternating electromotive force from external power source is transformed to the direct current power of 24V, utilize the integrating ampere hour meter be directly connected with AC/DC transducer to measure the consumes power of compounding machine.

In addition, proposing following image processing system, namely in the hope of going out the electricity that image processing system consumes, for the purpose of the countermeasure of support user, gerentocratic electric power saving, there is the function of display or total electricity usage situation.

In the past, by measuring supply voltage and the load current of primary side (the source power supply side before the transformer of image processing system), the consumes power of measurement image forming apparatus was carried out.Such as, in following document 3, disclose following technology, namely the time as electric power saving pattern is measured, according to the unit consumption electric power under the time measured and the usual power mode measured in advance, calculate imaginary power consumption during usual power mode, the difference of the consumes power of imaginary consumes power during usual power mode and electric power saving pattern is calculated as the electric power reduction value of electric power saving pattern.

In addition, in following document 4, disclosing following technology, namely calculating consumes power by measuring to supply from source power supply to the current value of image processing system main body and magnitude of voltage.In the art, when user have issued printing instruction, the view data being created on the printing instruction that user sends adds the view data of the view data of power information notice, and this view data is printed in the paper of regulation.

Document 1 Japanese Unexamined Patent Publication 2002-304092 publication

Document 2 Japanese Unexamined Patent Publication 2006-39443 publication

Document 3 Japanese Unexamined Patent Publication 2005-132045 publication

Document 4 Japanese Unexamined Patent Publication 2010-5809 publication

But there is precision this problem low by calculating the consumes power obtained in the technology of document 1.

Such as, power consumption during duplicating changes significantly according to copy mode.Because copy mode exists multiple.Such as, if the paper feed ports of the paper used in supply duplicating is different, then quantity, the kind of the motor used are different.In addition, when color mode, the photoreceptor of 4 looks rotates respectively, and on the other hand, when monochromatic mode, only the photoreceptor of 1 look rotates, and the power consumption of the motor thus making photoreceptor rotate changes significantly in color mode and copy mode.In addition, if antiquarian is different, then the actuation time of each parts is also different.In addition, power consumption also depends on the voltage of high-voltage power supply from one of the main formation as electronic photo process or the value of electric current significantly.Voltage or electric current are controlled by so-called image stabilization, decide suitable value according to environment for use.In addition, power consumption changes according to the variation of the environment such as temperature, humidity.Under low temperature environment, due to hardening of grease, the load torque of the parts that gear, bearing are such increases.Therefore also there is following situation, namely as the parameter for obtaining consumes power, having to environmentally prepare different values.

Therefore, the parameters such as above-mentioned fixed value A, B and C needed for the calculating of consumes power are multiple, in order to improve the precision of consumes power, need for the more parameter of quantification huge operation and design man-hour, thus impracticable.

And then deep problem is the process lasting the variation of the power consumption of change of accompanying image forming apparatus.For the load torque that the cleaning member generations such as bearing, photoreceptor or transfer belt cause because rubbing, owing to lasting change or durable change, this load torque changes.Therefore, even if print under identical pattern, before half a year, different from the state of present load before 1 year.Power consumption is different.

Therefore, as document 1, only set fixed value according to the using method (printing setting) of image processing system, the variation lasting the power consumption of change of accompanying image forming apparatus can not be evaluated.Suppose, what the fabricator of image processing system used image processing system studies machine, and the time of imposing devises fixed value, in the image processing system of reality using metal die volume production, can need micro-corrected parameter fixed value.Therefore, according to the scale revised, after the volume production of image processing system starts, the correction operation of parameter can be needed.If this correction operation spended time, then according to circumstances, can cause having to the state of affairs of selling of extension image processing system.

There is following problems in the technology of document 2, namely when the power consumption of each load for measurement image forming apparatus, needs the integrating ampere hour meter of the size arranging the power consumption according to each load by each load, can cause the complicated of device.

In addition, be that the power consumption of image processing system of representative has following feature with MFP.When the operating state of image processing system is in warming-up, image processing system, owing to carrying out the action etc. fuser being heated to the temperature specified, therefore will consume the electric power of the degree of hundreds of watt to thousand hundreds of watts continuously.When the operating state of image processing system is in printing, image processing system carries out the driving etc. for the motor printed, and therefore can consume the electric power of the degree of hundreds of watts continuously.Meanwhile, image processing system, owing to carrying out the temperature control action of fuser, therefore can consume the electric power of the degree of thousand hundreds of watts intermittently.When the operating state of image processing system be standby middle time, image processing system can consume the electric power of the degree of tens of watts continuously because of control circuit etc.Meanwhile, image processing system controls due to the temperature of fuser, can consume the electric power of the degree of thousand hundreds of watts intermittently.When the operating state of image processing system is in the electric power saving patterns such as park mode, image processing system because of president's time remainings such as control circuit portion consume the little electric power of the degree of several watts.

During with time shaft to power consumption value in each above-mentioned operating state, the ratio of the time of maximum consumption power state is few, and the ratio of the time of minimal consumption power state (electric power saving pattern) is the highest.

Therefore, such as when measurement 1 week or 1 month so long-term in consumes power time, the variation of power consumption is large, and the Measuring Device of power consumption needs precision can measure power consumption from low consumption electric power to the wide region of high flow rate electric power well.

Such as, if for the power consumption utilizing the power consumption metering circuit precision inserting primary side to measure wide region well, then power consumption metering circuit needs to have the performance with general tester same degree, thus complicated and this problem expensive of the formation that there is image processing system.In addition, when inserting power consumption metering circuit to primary side, need the testing circuit in power consumption metering circuit and insulation between the part that testing result is shown, thus complicated and this problem expensive of the formation that there is image processing system.Specifically, when being transformed to AD(analog digital based on by the current value of primary side) and the value that obtains calculates consumes power time, the variation of the current value that measure is large, and the measuring accuracy of the electric current of the AD transducer of the cheapness therefore about 10 bits is poor.

In recent years, the reduction target of the carbon dioxide of discharge, the concrete of consumes power represented with numerical value, became stricter to the requirement of the measuring accuracy of consumes power.But document 3 and 4 technology is not but considered completely for the deterioration of the measuring accuracy of the consumes power of the width with the electric power range that will measure.

When considering the power consumption of image processing system from this viewpoint of load change, except image processing system as described above operating state caused by variation except, also there is the kind of paper, environment is set or lasts the caused load change such as deterioration.Such as when paying close attention to fuser, except melting the fixing required energy of toner, also there is the heat taken by paper.This heat depends on the thickness of paper, the amount of moisture of paper significantly, therefore according to the kind of paper, and the heat variation needed for fuser.In addition, the load torque of the motor of image processing system is driven to depend on environment.Such as at low ambient temperatures, due to the hardening of grease etc. in motor, power consumption increases.And then, due to image processing system each parts last deterioration, the image processing system of the state of new product and long-term between uses after the load torque of image processing system there are differences, power consumption variation.

And then indispensable high-voltage power supply adjusts its output voltage, output current according to image stabilization action in electronic photo process.Therefore, the power consumption of high-voltage power supply is not constant.Cooling fans etc. are in order to realize mute, and usual non rotating, also by monitoring that temperature etc. controls it and rotates.

Here, prior art has the computing method of following power consumption, namely prepares in advance according to pattern and the number of original copy that will duplicate or the parameter of the power consumption of the number of paper that will print, uses this parameter to calculate power consumption.The difference of the power consumption that the method can cause because of the difference of pattern by appropriate accuracy computation.But the method is when calculating the absolute value of power consumption, and the parameter (information) that to need environmental baseline, durable condition, image forming conditions, paper type, paper thick etc. a large amount of, to improve the accuracy of detection of consumes power, then needs huge program.As a result, the exploitation of huge program is needed, for determining the checking operation of parameter.

That is, do not propose, when the accuracy of detection of the power consumption improving image processing system, to take into account the suitable electric measurement of cost of products and cost of development in the past.

[ summaries of the computing method of consumes power ]

Then, the summary of the computing method of consumes power is described.

Fig. 4 is the block diagram of the formation of the calculating of the consumes power of the image processing system representing one embodiment of the present invention.Formation when Fig. 4 represents that image processing system does not comprise after-treatment device 220.

1st power system calculation portion 103e gives the consumes power driving the measured value of the electric current of load portion 105 and after-treatment device 210 to calculate the 1st load group, i.e. driving load portion 105 and after-treatment device 210 based on supply.Specifically, the 1st power system calculation portion 103e gives the consumes power driving the measured value of the electric current of the motor of image processing system to calculate these motors based on supply.Paper transmits drive division 105a, photoreceptor drive division 105b, developer drive division 105c, ADF drive division 105e, other drive divisions 105f and aftertreatment drive division 210b to drive the motor of image processing system to refer to.In addition, the 1st power system calculation portion 103e calculates the consumes power of high-voltage power supply 105d to the measured value of the electric current of high-voltage power supply 105d based on supply.1st power system calculation portion 103e is by directly measuring electric current to calculate owing to forming relevant each action (number of prints, antiquarian, single-side/double-side pattern, colour/monochrome pattern, paper supply level or aftertreatment pattern etc.) and the consumes power of the variation of the driving load system of action under various conditions to image.In addition, the 1st power system calculation portion 103e also can carry out the consumes power of computational load to the measured value of at least any one party in the voltage of load or electric current based on supply.

2nd power system calculation portion 103f calculates the 2nd load group, i.e. fixing heater 83(fixing heater drive division 104 based on the conduction time of the electric power connected to fixing heater 83 and fixing heater 83) consumes power.2nd power system calculation portion 103f predicts that (calculating) needs the consumes power of the fixing heater 83 of large electric power at short notice.

3rd power system calculation portion 103g is based on the operating state of image processing system and the consumes power that calculates the 3rd load group actuation time, namely operate display control unit 103a, image control portion 103b, drive the total of load control part 103c and fixing heater control part 103d.3rd power system calculation portion 103g predicts that (calculatings) needs the operation display control unit of little electric power and carries out the consumes power of each control part of control of each load as control object in for a long time.

Electric power total portion 103i, by adding up to the consumes power that calculated by the 1st ~ 3rd power system calculation portion 103e ~ 103g, decides the consumes power of image processing system entirety, and notifies the consumes power that determines to display part 102.Display part 102, based on notified consumes power, carries out display and the total of electricity usage situation, and informs the user power consumption information.

Fig. 5 is the block diagram of the formation of the variation of the calculating of the consumes power of the image processing system representing one embodiment of the present invention.Fig. 5 represents the formation during power consumption calculating after-treatment device 220 further.

With reference to Fig. 5, the 4th power system calculation portion 103h based on after-treatment device 220 operating state and predict (calculating) power consumption as the after-treatment device 220 of the 4th load group actuation time.The such usual running rate of the 2nd peripheral unit of after-treatment device 220 is low, therefore the driving system loads of the 2nd peripheral unit consumes power based on after-treatment device 220 operating state and predict actuation time.

Electric power total portion 103i, by adding up to the consumes power that calculated by the 1st ~ 4th power system calculation portion 103e ~ 103h, decides the consumes power of image processing system entirety, and notifies the consumes power that determines to display part 102.Display part 102, based on notified consumes power, carries out display and the total of electricity usage situation, and informs the user power consumption information.

In the computing method of above-mentioned consumes power, by coordinate the actual conditions of the power consumption of image processing system, last or the change of durable power consumption, divide into and utilize calculating calculate the part of consumes power and utilize actual measurement to calculate the part of consumes power, calculate consumes power, thus the method that realization easily designs, precision is high.

When the consumes power of computed image forming apparatus, not only need to consider to print the consumes power in action, also need to consider also to comprise standby in consumes power, consumes power in park mode comprehensive consumes power.From this viewpoint, preferably with being called as TEC(TypicalElectricityConsumption) consumes power of value discusses.TEC value is after the amount that specifies has carried out printing action, and the consumes power during printing action specified is carried out in the stopping via regulation again, and also assume that imagination night, the form of time of park mode on off-day measures consumes power.

If analyze the consumes power forming TEC value, then it is detailed content as follows.

Consumes power under park mode ... .29%

Consumes power (drive division removing fixing heater) in printing ... .13%

Consumes power (control part removing fixing heater) in printing ... .3%

Consumes power (fixing heater) in printing ... .55%

After print out task terminates, print if do not perform next, then shift to park mode (electric power saving pattern) on the opportunity of regulation.In addition, because night, off-day also do not perform printing, therefore for shifting to the state of long-time park mode.The accumulative consumes power consumed under these park modes accounts for 29% of TEC value.In this situation, driving load portion, fixing heater do not carry out action, and therefore the consumes power of image processing system entirety is the consumes power of only control part.On the other hand, when receiving print instruction from dormant state, image processing system carries out warming-up action, while warming-up completes, carry out printing action, if print release, then returns park mode.The consumes power accounting for the driving load portion of the aggregate-value of the consumes power of this series of action, control part and fixing heater is respectively 13%, 3% and 55%.

When park mode, image processing system only remains the function of the irreducible minimum for accepting print instruction, and control in addition stops.Therefore, the variation of power consumption is few.Therefore, when for dormant state, consumes power can be obtained well according to its of precision actuation time.

The consumes power of the control part in printing calculates based on " state according to the different image procossing of printing model " and " actuation time of printing model ".

The consumes power of the driving load portion in printing easily produces variation because of resistance to the waiting so long of environment, device.Therefore, the electric current driving the consumes power of the power-supply system of load portion (being in most cases 24V) to go out based on actual measurement calculates.The measurement of preferred electric current is carried out to control synchronous cycle in cycle (cycle of master routine) of the action of motor with control part.Drive load portion to judge will to be unlocked or to be closed by specified period by control part, carry out opening or closing according to judged result.Therefore, the change of electric current becomes the action corresponding with this cycle.

The consumes power of the fixing heater in printing calculates based on " the rated consumption electric power of fixing heater " and " actuation time of fixing heater ".The rated consumption electric power of fixing heater is managed with the component tolerance of the difference of the power consumption of actual well heater as well heater, therefore can carry out accuracy control.

Here, in order to prevent flowing through surge current when opening or close the transition of fixing heater, or in order to prevent from resulting from the variation in voltage of the primary side of opening or closing, sometimes when carrying out lighting or extinguishing, gradually make power consumption change.In this situation, added the calculating of correction by the calculating of the consumes power to fixing heater, the calculating of correct consumes power can be carried out.The control cycle that actuation time and the open and close carrying out fixing heater of preferred fixing heater control is synchronously measured.

As described above, the current value based on actual measurement calculates the consumes power driving load portion, predicts the consumes power of part in addition, thus precision can obtain consumes power well based on operating state prediction.

Fig. 7 is the circuit diagram of the computing method of consumes power for illustration of the driving load portion 105 performed by the 1st power system calculation portion 103e and after-treatment device 210.

With reference to Fig. 7, power supply unit 106 comprises low-tension supply 106a.Low-tension supply 106a is connected with multiple load LD is parallel with one another.Low-tension supply 106a is specified out-put supply, by the rated voltage (such as 24V) that the voltage transformation of primary side (the source power supply side before power supply unit 106) is primary side (the load LD side after power supply unit 106), supply electric power with the voltage after converting to each load LD.Load LD is the parts corresponding with each drive division or after-treatment device 210 that drive load portion 105.Power supply path between low-tension supply 106a with each load LD is connected with current sense resistor 301.The electric current behind the electric current interflow making to flow through all load LD is flow through in current sense resistor 301.

1st power system calculation portion 103e temporally T1(s) to such as the electric current flowing through current sense resistor 301 being carried out the value after AD conversion, i.e. electric current M1(A) (the AD transformed value of 24V current monitor) carry out the measurement (sampling) of times N 1.Time T1 is the sampling period, and times N 1 is sampling number.Time T1 and times N 1 amassing as 1(s respectively according to time T1 and times N 1) mode set, be such as stored in ROM333.In the present embodiment, as shown in Figure 8, the time, T1 was set to 5(ms), times N 1 is set to 200(time).

1st power system calculation portion 103e, based on the rated voltage measuring the electric current M1 that arrives and primary side, calculates every 1(s) the consumes power (Ws) of primary side.The open and close state of each load LD is intricately change in printing sequence, is therefore flow through the electric current of current sense resistor 301 by actual measurement, based on actual measurement to electric current calculate the consumes power of primary side, the precision of consumes power can be made to improve.In addition, preferably the consumes power of primary side is scaled the consumes power (Ws) of primary side by the 1st power system calculation portion 103e.Low-tension supply 106a is used for changing conversion efficiency according to the size of electric current (electric current of primary side).When the consumes power of primary side is transformed to the consumes power of primary side, preferred example conversion efficiency table as shown in Figure 9.Afterwards, the 1st power system calculation portion 103e notifies computing information to electric power total portion 103i.

Figure 10 is the process flow diagram of the computing representing the consumes power that the 1st power system calculation portion 103e performs.Process flow diagram shown in Figure 10 is performed as the subroutine of the process in the step S17 of Fig. 6.

With reference to Figure 10, the 1st power system calculation portion 103e metered flow excess current detects the electric current M1(S101 of resistance 301), and electric current M1(S103 is added on integrating electric E1).Then, the 1st power system calculation portion 103e calculates variable n and whether reaches 200(and whether have passed through 1(s) time) (S105).

In step S105, when being determined as variable n and reaching 200 (in S105, yes), the 1st power system calculation portion 103e, by with 200 removal integrating electric E1, carrys out the 1(s of calculating current M1) between mean value E(S107).Then, the 1st power system calculation portion 103e, based on mean value E and rated voltage (24V), calculates every 1(s) the consumes power N(S109 of primary side).Then, the consumes power N of primary side is transformed to every 1(s by the 1st power system calculation portion 103e) the consumes power A(S111 of primary side).In step S111, example conversion efficiency table as shown in Figure 9, obtains conversion efficiency when electric current is mean value E, by removing the consumes power N of primary side by the conversion efficiency obtained, calculates the consumes power A of primary side.Then, the 1st power system calculation portion 103e notifies the consumes power A(S113 of primary side to electric power total portion 103i), the value of variable n and integrating electric E1 is reset (S115), and returns.

[ computing method of the consumes power in the 2nd power system calculation portion ]

Then, the computing method of the consumes power of (fixing heater 83 is the situation of halogen heater) the 2nd power system calculation portion 103f when being halogen fuser to fixing device 8 are described.

When fixing device 8 be the use of halogen heater (Halogen lamp LED) fuser, namely halogen fuser time, the electric current flowing through fixing heater 83 is being suppressed under the following state of rated current (such as 15A or 20A), warm-up period demand fulfillment defined terms (product specification).Therefore, the halogen heater of fixing heater 83(used in copy machines) in the power consumption of the reality for rated electrical or the heat that produces of fixing heater 83 be strictly managed.Therefore, fixing heater 83 is that the variation of power consumption under the state of opening is little.If be conceived to this fact, then the consumes power as the fixing heater 83 of halogen fuser correctly can calculate based on the rated electrical of fixing heater 83 with to the conduction time of fixing heater 83.

Figure 11 is the concept map of the computing method of consumes power for illustration of the fixing heater 83 of fixing device 8 performed by the 2nd power system calculation portion 103f during halogen fuser.

With reference to Figure 11, when carrying out common control to fixing device 8, as shown in (a), 2nd power system calculation portion 103f using the rated electrical of fixing heater 83 as the connection electric power to fixing heater 83, by the rated electrical of fixing heater 83 and the long-pending consumes power calculating fixing heater 83 of conduction time.On the other hand, when fixing heater is opened or when closing, for the purpose of the damage of the fixing heater 83 caused to prevent surge current, sometimes carry out the control (rise (Throughup) controls) that the electric current flowing through fixing heater 83 is increased lentamente or the control (decline (Throughdown) controls) that the electric current flowing through fixing heater 83 is reduced lentamente.When carrying out these and controlling, as shown in (b), the 2nd power system calculation portion 103f based on after the action just starting fixing heater 83 and action just stop before transition state under the change of power consumption of fixing heater 83 revise consumes power.Specifically, 2nd power system calculation portion 103f, by deducting the correction consumes power AM1 risen when controlling and the correction consumes power AM2 declined when controlling from the rated electrical of fixing heater 83 and the long-pending of conduction time, calculates the consumes power of fixing heater 83.

In addition, the 2nd power system calculation portion 103f also can only based on action just start after and action just stop before in any one transition state revise power consumption.

Then, an example of the computing method of the consumes power of the fixing heater 83 when fixing heater 83 is made up of long well heater and short heater 2 halogen heaters is described.Long well heater and short heater rated electrical separately as shown in figure 12, is 1180(W) and 790(W).

Figure 13 is the figure of the typical ignition mode representing fixing device 8.

With reference to Figure 13, when fixing heater 83 is opened at moment t1, by control of rising, the power consumption of fixing heater 83 and time are in direct ratioly increased to rated electrical.If the power consumption of fixing heater 83 is increased to rated electrical at moment t2, then fixing heater 83 is the state entirely lighted, and power consumption is constant.When fixing heater 83 is closed at moment t3, control by declining, the power consumption of fixing heater 83 and time power consumption when being reduced to closedown in direct ratio.During closedown, power consumption is 500(W for long well heater), be 335(W for short heater).If the power consumption of fixing heater 83 is power consumption when moment t4 is reduced to closedown, then fixing heater 83 extinguishes entirely.
